An Australian energy company told an 85-year-old pensioner it owed him $10,763 after overcharging him; two months later, it claimed he owed money and sent debt collectors

An electricity bill is rarely something most households look forward to receiving, but for an 85-year-old pensioner in South Australia, correspondence from his former energy provider brought a particularly confusing turn of events. After leaving ENGIE over rising electricity costs, Bill Nedeff was informed that the company had discovered he had been overcharged by more than $10,000. He was asked to claim the money back. However, the figures began changing, and the credit eventually turned into a debt. By August 2025, Nedeff was being told he owed the company money, with debt collectors also contacting him. It took months of questioning before ENGIE acknowledged its mistake.How an Australian pensioner's $10,763 electricity refund became a debtNedeff's dealings with ENGIE had already ended when the company contacted him in June 2025. The pensioner, who lives with his wife at Encounter Bay, south of Adelaide, had switched providers after becoming increasingly concerned about the cost of his electricity bills. ENGIE said an error had been identified in his account, resulting in an overcharge of $10,763.27, as reported by ABC News.The company apologised and instructed him to request a refund. But the amount did not remain unchanged for long. By August, ENGIE had reversed its position altogether, informing Nedeff that he owed it $1,120. Letters from a debt collection agency followed, adding another complication to what had started as a request for a refund.The changing figures left Nedeff struggling to understand his account. He told ABC's 7.30, "I was having a few sleepless nights over it and that wouldn't be just, say, tonight and tomorrow night, it was over a number of weeks.”Australian family challenges ENGIE after reviewing years of electricity billsNedeff's daughter, Fiona Han, became involved as the family tried to establish where the figures had come from. They approached the South Australian Energy and Water Ombudsman, seeking an explanation for the contradictory statements. By November 17, the amount ENGIE claimed was outstanding had fallen from $1,120 to $280.Although Nedeff considered settling the smaller amount, Han was reluctant to accept the revised bill without a proper breakdown. She had seen the original letter acknowledging the overcharge and believed the company needed to explain how an account that had been in credit could suddenly become a debt. The family also began examining years of electricity statements, many of which had been kept in shoeboxes.Reportedly, Nedeff had installed 30 solar panels on his roof, making the growing charges difficult for the family to reconcile. According to the bills they examined, his peak electricity rate had risen from 43 cents per kilowatt-hour in June 2022 to 75 cents the following month. By 2024-25, it had reached 83 cents per kilowatt-hour, before he left ENGIE.On December 9, 2025, the company finally confirmed that Nedeff did not owe it anything. Instead, its revised calculations showed that he had been overcharged by $2,470. The amount was considerably lower than the original credit of $10,763.ENGIE faces further scrutiny over billing errors and customer complaintsIn its response to ABC's 7.30, ENGIE attributed the problem to mistakes made during a manual adjustment of Nedeff's account."We have found an agent has made manual data entry errors in the process, resulting in incorrect bill amounts being sent to Mr Nedeff and one other ENGIE customer. We're very sorry for the confusion this caused and are working with the ombudsman and customers to refund the correct amount and resolve this issue."ENGIE acknowledged that the error had caused confusion and apologised. It also said it was working with the relevant customers and the ombudsman to arrange the correct refunds and settle the matter. The incident came amid wider questions about the retailer's billing practices in South Australia. In August 2025, ENGIE had been required to correct electricity bills for as many as 3,000 customers after acknowledging that they had been overcharged.Reportedly, the company was also facing regulatory scrutiny elsewhere. In late November 2025, Victoria's Essential Services Commission fined ENGIE $1.2 million following an investigation into delays in responding to customer complaints about billing.ENGIE separately acknowledged, "We've made meaningful changes to staffing, training and key customer processes and seen a significant improvement in service performance as a result.”Electricity rate increases raised further questionsFor Han, the dispute was not limited to the incorrect refund and the debt collection letters. Her examination of the household's older bills suggested that her parents had been paying substantially higher electricity rates for several years.South Australian Energy Minister Tom Koutsantonis also criticised the way the company had handled Nedeff's account. He said the errors risked undermining customers' confidence in electricity retailers, particularly when people could no longer be certain that the amounts on their bills were accurate.Koutsantonis argued that customers should not have to question every charge simply to establish whether they were being billed correctly. He also raised concerns about the commercial incentives of energy retailers, suggesting that customer service was not always receiving the attention it required.Experts call for stronger protections against the electricity market's 'loyalty tax'Ron Ben-David, a former chair of Victoria's Essential Services Commission who now works at Monash University Business School, described the practice as a 'loyalty tax'. His argument is that customers who rarely compare electricity plans can gradually end up paying higher rates, sometimes without realising how far their costs have moved from the available market offers. Figures from the Australian Competition and Consumer Commission's 2025 Electricity Inquiry Report found that 73.3% of Australian households were not on the best available electricity deal.Ben-David has argued for a consumer duty that would require energy retailers to consider customers' interests when offering and managing contracts. Rather than leaving households to navigate an increasingly complicated market, companies would have a greater responsibility to identify plans suited to individual circumstances.For Nedeff, the dispute eventually ended with ENGIE acknowledging that he had been overcharged, rather than owing the company money. But the months between the original refund letter and the final correction involved changing bills, repeated requests for explanations and contact from debt collectors.Disclaimer: This article is based on information publicly available online.
